What has Cassini discovered so far about Saturn’s rings?

Cassini has taken the most detailed pictures ever of Saturn’s rings, and the structures that make the rings so large and complex, yet stable and beautiful. Cassini’s discoveries include new ringlets, new moons near the rings, a tiny moon stealing particles from the F ring, another moon (Enceladus) adding particles to the E ring, and features resembling waves, wakes, braids, straw, and rope.
